Governed by the lantern epoch-validation scheme, this mechanism ensures that identity-forgery attacks yield strictly negative expected utility through prohibitive capital lockups, mathematically sustaining Byzantine fault tolerance in Nash equilibrium.","stamp":1,"from":"poa1CuH3Mck1XDRKfYzwDVZDBt7nABZDgAWsiSET4LGqUKCX","nonce":4,"parents":["65d791859f5e7f39be344f7a25381be43af21364a4b6d9e61d017cd3d946db65","247c8a9fb217baaf95bf00fb73b7dc76e081f5f06410e8610519d4cb77116235"],"ts":1792946262,"cid":"poa-mainnet-1","sig":"3PsfhaNZSn4BFWVWagHhjVja2e3P1c2JD3UpthGgL96ayT1mZhwg4f5BkLHf3K3K3qMeM8UsCEkWQvpaoDYfPVSy"},"checkpointed":{"height":67872,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T07:27:41.373Z","checkpoint_height":67872,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
